The present invention is a construction method and structure to compensate for the shortcomings caused by the weight and excess weight of the material has a conventional floor heating method, the extension of the construction period, more specifically, the wet method by the foam concrete method is excessive weight Due to various disadvantages such as the risk of water leakage, prolonged construction period, and sound insulation and poor insulation, it is easy to apply to high-rise buildings. The structure relates to forming a first air layer by first using an elastic support, and to forming a second air layer by using unevenness in which the upper and lower surfaces are alternately opened in a second manner, thereby making the floor double and heavy and soft. The heavy shocks that occur when a dirty object falls, as well as when a light, hard object falls It relates to a completely dry structure between floors of multi-unit houses that effectively blocks all of the light impact sounds.

In general, multi-unit buildings such as apartments or villas are designed to prevent noise between floors and floors so that each occupant's life can be protected from noise by preventing shock or noise generated between floors from being transmitted to the lower or upper floors. It's a fact that technology is becoming commonplace.

As described above, a technique for preventing interlayer noise includes noise or impact sounds generated between floors through an interlayer floor structure for preventing transmission of interlayer noise and impact sounds to Utility Model Registration Nos. 287084, 290830, and 297962. Techniques have been proposed to significantly reduce the transmission to the upper layer along this lower layer or wall, but these techniques are interlayered due to the adverse effect of the impact between the finishing mortar layer and the flooring (hardwood or marble, etc.) installed thereon. There was a problem that the noise is further amplified.

That is, the currently proposed technique to prevent the interlayer noise is to reduce and block the interlayer noise through the dustproof and soundproof structure from the concrete slab layer to the finished mortar layer. However, the impact or noise generated when the topmost floor mortar layer of the floor structure and the flooring material (such as hard floor or marble) finally installed on each other are amplified and transmitted to the room or the lower floor.

In addition, the finishing mortar layer is excessive in the amount and weight of the material, the construction period is very long or often extended depending on the weather or weather.

In addition, in the interlayer floor structure, because the finishing mortar layer is uneven plaster smoothness is somewhat bent and vertical deviation occurs, there is a problem that a floating phenomenon occurs when installing a hard floor or marble flooring. Therefore, as well as the impact and noise generated by the lifting phenomenon, cracks or damage to the flooring is frequently generated.

In addition, if only the flooring material is installed on the finishing mortar layer, the hard impact of the flooring material and the finishing mortar layer is transmitted directly to the body through the foot when running or walking indoors. There is a problem that can put pressure.

In addition, the existing floating board is not configured to support the load on each of the edges and the center portion, which is a structure that expands and contracts in response to the upper pressure, which causes a problem of walking and noise is generated.

Finally, according to such a floor structure, the construction period is too long, there is a difficulty in removing the entire floor structure when attempting to repair or remodel after the construction is made.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to be able to construct even in a high-rise building, to provide a complete dry structure between floors of a multi-family house easy to repair after construction. It is.

Another object of the present invention is to increase the noise absorption rate of the inter-layer noise, to provide a completely dry inter-layer structure of a multi-family house having a multi-structure that blocks not only heavy impact sound but also light impact sound.

Another object of the present invention is to reduce the weight and weight of the material by using a fully dry prefabricated PC slab to reduce the manpower required for construction, minimize the construction period, the construction of the apartment that can be built regardless of the season To provide a completely dry structure between the floors.

Still another object of the present invention is to provide a completely dry structure between floors of a multi-family house in which the thickness of the floor structure is not thick but the floor structure is not lifted.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the complete dry floor structure of a multi-family house according to the present invention having the configuration as described above will be described in detail.

As shown in FIG. 1 or FIG. 2, the inter-floor complete dry structure 100 of the multi-family house according to the present invention is installed at a predetermined interval on the floor slab 102 forming the bottom surface of a residential building, and the first air layer 104. A plurality of elastic support parts 110, a hard inorganic board 120 supported by the elastic support part 110, and soft to be stacked on top of the inorganic board 120 ( soft) a first sound insulating pad 130, a floating board 140 stacked on top of the first sound insulating pad 130, and forming a second air layer 134, and a stacking on top of the floating board 140. A soft second sound insulation pad 150, a PC slab 160 installed on the second sound insulation pad 150, and a finishing material 170 stacked on the PC slab 160. It is configured to include.

The elastic support 110 is to support the completely dry structure 100 from the top of the floor slab 102, and evenly distributes the load of the completely dry structure 100 to the floor slab (102). However, when the complete dry structure 100 is slumped while walking, pedestrians may feel uncomfortable or uneasy, and should be installed at appropriate intervals.

In the embodiment of the present invention, as shown in Figures 3 and 4, the elastic support 110 is disposed one at each corner and one in the center within the range of 600mm × 400mm, in order to prevent bending or settlement Eight elastic supports 110 are further installed around the central elastic support 110 in a substantially circular or rectangular shape.

The elastic support 110 is used as a synthetic rubber having an elastic force, if the shrinkage force is too high because it can reduce the support force by using for a long time, using EPDM (Ethylene Propylene Diene Monomer) as the main raw material mixed with other mixture It is preferable.

In addition, SBR, CR, EPDM, NBR, etc. can be used as synthetic rubber, and natural rubber (NR), ethylene vinyl acetate copolymer (EVA), polyethylene (PE), polypropylene (PP), polystyrene (PS), PVC foam or the like may be used.

As shown in FIG. 2, a first air layer 104 having a thickness of 30 mm is formed between the bottom slab 102 and the inorganic board 120 by the elastic support 110. Finally, the impact sound transmitted from the upper part of the completely dry structure 100 is weakened so as not to be transmitted to the floor slab 102, and at the same time, it performs a thermal insulation function.

If the elastic support 110 is in contact with the floor slab 102 is large, the horizontal adjustment of the completely dry structure 100 may be worse, so as to effectively support the load of the upper portion, so that the completely dry structure 100 does not lift. In order to have a reverse conical shape of the ordinary light narrowing narrower diameter from the top to the lower as shown in FIG. For example, the upper diameter is about 30 mm, and the lower diameter is preferably about 17 mm. If the floor smoothness is not perfect, you can strengthen the floor smoothness with stone powder.

The air layer 104 serves to block the transfer to the lower layer by absorbing and canceling the shock or noise generated in the upper layer by forming an air film, and additionally prevents heat loss.

The inorganic board 120 is to increase the walking feeling by enhancing the durability. It is manufactured in the thickness of 9mm using inorganic ingredients such as magnesium and silicon as the main raw materials, and is excellent in strength and hardness to reinforce the strength of the completely dry structure 100, and at the same time, it is completely dry and flame retardant, which is effective for preventing fire. In the embodiment of the present invention, a magnesium inorganic board is mainly used. Although the magnesium inorganic board is effective in non-combustible and flame retardant, various inorganic materials such as ocher may be further included to further reinforce it and increase functionality such as insect repellency.

The completely dry structure 100 of the present invention is characterized in that it is designed to be assembled in a mat shape, as described above for the construction and durability, the shape of the rectangular or square within the range not exceeding 700mm in length and width as described above, respectively.

The first sound insulation pad 130 and the second sound insulation pad 150 are intended to mitigate the shock transmitted to the inorganic board 120, and are molded of a soft foamed synthetic resin product to absorb the impact and reduce noise. Among them, expanded polypropylene (Expanded Poly Propylene (EPP)), expanded polystyrene (Expanded Poly Styrene (EPS)) or a mixture thereof is preferable. The thicknesses of the sound insulation pads 130 and 150 may be slightly different. The first sound insulation pad 130 is about 4 mm, and the second sound insulation pad 150 is made to be thinner than 2 mm thick. desirable.

As described above, the soft sound insulating pads 130 and 150 perform a soundproof function to block the shock sound by a predetermined elastic force and a dustproof function to suppress vibration. In particular, the sound insulation pads (130, 150) is effective in blocking the light impact sound, such as shoes of the upper floor.

As shown in FIG. 5 and FIG. 6, the floating board 140 facilitates the construction of the pipe 142 and prevents the heat transferred from the pipe 142 from being lost to the bottom. As illustrated in FIG. 7, a plurality of cylindrical support parts 144 are vertically formed on the floating board 140 to form a second air layer 134, and the cylindrical support parts 144 are formed. At least one through hole 149 is formed at an end of the crest, and a seating part 146 on which the pipe 142 is seated extends back and forth and left and right between the supporting parts, and the seating part 146 is further provided. Another through hole 149 is formed to protrude, and a plurality of diaphragms 148 are formed across the edge and the center.

In addition, the diaphragm 148 functions to allow the floating board to be seated on the first sound pad or the inorganic board, thereby enhancing a walking feeling of a pedestrian.

In addition, the through hole 149 may be installed at any one side of the floating board, as well as the end of the cylindrical support 144, the seating portion 146, and serves as a passage of air completely dry structure Can improve the sound insulation performance.

As such, a second air layer 134 having a thickness of 30 mm is formed in the cylinder of the support 144 to cushion the shock sound transmitted from the upper PC slab 160. That is, the second air layer 134 serves to prevent a so-called 'sound bridge' phenomenon in which the impact sound transmitted from the PC slab 160 is transmitted to the inorganic board 120.

On the other hand, the lower portion of the floating board 140, except for the supporting portion 144 is provided with a heat insulating material 180 to prevent the heat of the pipe 142 is discharged to the bottom. The heat insulator 180 is filled by the pipe seat 146 to the bottom of the floating board 140 under the seat 146.

In the present embodiment, the floating board 140, the heat insulator 180, and the second sound insulation pad 150 are integrally provided by various fastening means or adhesives in the manufacturing process to form the second air layer 134. Done.

Another feature of the present invention uses a prestressed concrete (PC) slab 160 manufactured at the factory instead of plastering mortar. The PC slab 160 is molded into a plate-like shape having a thickness of 30mm. Therefore, since there is no need to assemble or dismantle the formwork by directly assembling and constructing the site using the already manufactured slabs, the construction period is significantly shortened.

As shown in Figure 8 and 9, the PC slab 160 is provided with a grid-like joint 162 at its edge for assembly, one side is provided with a stepped surface in the lower corner and the other in the upper corner It has a stepped surface.

The finishing layer 170 is used, such as vinyl or paper board, wood, natural stone, tiles.

As described above, in order to prevent noise between floors caused by impacts by absorbing or buffering shocks generated between floors in apartments such as apartments or villas, an elastic support part made of synthetic rubber of EPDM is formed on a floor slab. Stacking a plurality of hard magnesium inorganic board in a state arranged in the first air layer to form a second air layer on the inorganic board using a concave-convex floating board of the upper and lower surfaces alternately open. In addition, it can be seen that the technical idea is to form a double structure of the floor by forming a PC slab on the floating board and to form a double air layer between the floors.

10 to 18 shows a completely dry structure of a multi-family house according to another embodiment of the present invention, there is a difference in that the square structure is not a rectangular structure as shown in Figures 1 to 9 above, and also, floating Except for the fact that the through-hole is not formed on the board and the arrangement of the elastic support is different, other structural features have been described in detail based on the above-described FIGS. 1 to 9, and thus the following description will be omitted.
